How can you tell when your vehicle needs to be brought in for its next safety inspection?

The selected answer is correct as it refers to the safety inspection plate with the test sticker, which is the primary way to determine when your vehicle needs its next safety inspection. In Germany, the test sticker indicates the validity period of the last inspection and when the next one is due.

However, it's essential to note that while this is a primary method, reading the entry made in the registration certificate Part I also provides important details about the vehicle's last inspection date and necessary future inspections.

Combining these methods ensures that you stay compliant with German traffic laws and maintain your vehicle's safety standards, as both the inspection plate and registration documents serve as important references for keeping the vehicle up to date with required inspections.
